The European arm of the automaker isn't changing anything about
the car itself, just the paint job. It's using super-hydrophobic
and oleophobic paint that repels water and oils, so dirty water
that hits the car never sticks and never needs to be cleaned off.

Nissan is testing the paint, sold by UltraTech International Inc,

rain, frost, and sleet.

This isn't a brand new idea — you can buy similar coating without spending a

says it doesn't plan to make the technology standard, but it
"will continue to consider the coating technology as a future
aftermarket option."
